I maybe barking up the wrong tree, but I think I got your error.
It took a bit of rooting around.
Normally if the scalar is just a normal hash it should autovivify.
Here is an autovivification example:
I got your error only when I tried to turn an undef into a hash reference explicitly:print %{$foo->{a}->{d}} So maybe making it into a two step process:
Results:my $foo = { }; $foo->{a}->{b}->{c}->{d} = 1; use Data::Dumper; print Data::Dumper->Dump([$foo],['foo']);
All those keys were undef, but now they were created just by asking for them.$foo = { 'a' => { 'b' => { 'c' => { 'd' => 1 } } } };
I got your error only when I tried to turn an undef into a hash reference explicitly:print %{$foo->{a}->{d}} So maybe making it into a two step process:
that might take care of your errors. If I totally missed your problem, sorry.my $bar = $foo->{a}->{d}; print %$bar if $bar;
